This technical report describes the contents of calibration tapes for various broadcast VTRs. The objective in using a calibration tape is to adjust the machine so that it will give optimum reproduction of a first-generation verified recording. The calibration signals recorded under controlled conditions on a machine corresponding to the relevant VTR standard. The calibration procedure involves playing back the tape while making the necessary operational adjustments as described in the manufacturer's manual. In addition, trial recordings and the adjustment of the record chain settings should lead to a similar play-back quality as obtained from the calibration tape.

The methods of measurement described in this International Standard concern the assessment of the performance of non-broadcast video tape recorders of the so-called "colour under" type for domestic use. This standard defines test signals, measurement set-ups and measurement conditions for non-broadcast video tape recorders of the so-called "colour under" type for domestic use, so as to make possible the comparison of the results of measurements. Specifying limiting values of the various quantities for acceptable performance is not an object of this standard. The methods of measurement are designed to make possible the assessment of the performance of the complete recorder by using the input/output terminals of the device. NOTE - Measuring methods for consumer camcorders (camera-recorders). are under consideration.

This part of IEC 61834 is an extension of the SD specification (SD mode) and covers the features necessary to enable a DVCR to record and reproduce PALplus signals. While all DVCRs must have the capability of recording and/or playback in SD (SP) mode, PALplus capability is optional. For this Part 8, the data structure of a track is defined by APT = 000b which consists of four areas as described in 4.3.2 in IEC 61834-1 and AP1 = AP2 = AP3 = 000b. There are two methods for recording the PALplus signal on a DVCR: - method 1: record the partially encoded PALplus signal; - method 2: record the completely decoded PALplus signal. This part is concerned with "Method 1" (baseband helper recording) as this requires an extension to the DVCR SD specification IEC 61834-2. For "Method 2" the DVCR is equipped with a built-in PALplus decoder and the SD specification IEC 61834-2 applies unchanged.

This part of IEC 61834 specifies the content, format and recording method for the data blocks forming the helical records on the tape containing audio, video and system data. This part describes the specifications for the recording of single DVB programmes. The DVB data is delivered to the digital video cassette recorder via a digital interface or by a built-in tuner (IRD). The DVB data consist of an MPEG2 transport stream containing one or more programmes. In DVB, the MPEG2 MP@ML is specified to encode the video signal. The maximum bit rate for the video signal is 15 Mbps. One programme may consist of one video bit stream or several audio bit streams and data bit streams. Due to the varied bit rates of single DVB programmes, several recording modes are specified in order to make efficient use of the storage capacity of the digital video cassette recorder. In addition to the normal play data stream of DVB recording, one or two special trick play data streams may optionally be generated and recorded in the video area. In this part 9, the data structure of a track is defined by APT = 000b which consists of four areas as described in 4.3.2 of IEC 61834-1 and AP1 = AP3 = 000b. The data structure of MIC is the same as in clause 10 of IEC 61834-2
